p320

The SIG Sauer P320 is a modular semi-automatic pistol made by SIG Sauer, Inc., the company's American branch. It is a further development of the SIG Sauer P250, utilizing a striker-fired mechanism in lieu of a double action only hammer system. The P320 can be chambered in 9×19mm Parabellum, .357 SIG, .40 S&W, and .45 ACP, and can be easily converted from one caliber to another; a change from .357 SIG to .40 S&W requires only a barrel change; a change between 9mm to .357 SIG or .40 S&W and vice versa are accomplished using a caliber exchange kit.
The P320 chambered in 9×19mm Parabellum was introduced in the North American market on 15 January 2014, followed by the .45 ACP compact model at the SHOT Show in January 2015. On 19 January 2017, it was announced that a customized version of the SIG Sauer P320 had won the United States Army's XM17 Modular Handgun System competition. The full-sized model will be known as the M17 and the carry-sized model will be known as the M18.
